ORE-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 349,504, dated SeptemberZl, 1886.

Application filed April 537, 1886. Serial No, 200;289. (N0 model.)

To all whom it may concern.-

Be it known that I, HENRY G. KRAUSE, of Lake Linden, in the county of Houghton and State of Michigan, have invented a new and Improved Ore-Separator, of which the following is a full, clear, and exact description.

My invention relates to machines for separating and grading ores, and has for its object to provide a simple, comparatively inexpensive, and effective machine whereby ores of various kinds may be washed and concentrated, and the valuable mineral and the tailings separately and closely graded, and with economy of time and labor. r.

The invention consists in certain novel features of construction and'combinations of parts of the machine, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of my improved oreseparator. Fig. 2 is an enlarged detail vertical sectional elevation showing the drivinggearing by which the pan is agitated bodily. Fig. 8 is a-vertical sectional elevation taken on the irregular linear 00, Fig. 1. Fig. 4 is an end View of the front end of the separator; and Fig. 5 is a detail vertical sectional elevation across the mineral and tailings boxes, and taken on the line 3/ y, Fig. 1.

The separatorpan A is formed of a fiat plate, a, having downturned aprons a a respectively, at the tail and head edges, and upturned flanges a a at the front and back ends, respectively. The front end, A, of the pan lies about at a right angle with the tail A of the pan, and the head A runs obliquely from the corner B of the pan toward the back end, 0, of the pan, and preferably at an angle of from twenty-five to thirty degrees to the tail A (See Fig. 1.)

To the bottom of the pan-plate a is fixed a marginal stiffening-frame, a to which is fastened a bearer-plate, a, having lugs a a to and between which is j ournaled a gimbal-ring, D, which fits loosely upon a flange, e, of a plate, E, which is held to the top of a shaft, F, journaled in a frame, G, fixed to the floor of the mill-house. The plate-E is slotted at e for the passage of ascrcw-bolt, e, which also passes through washers or clamp-disks e e, above and below the plate, on its way to the shaft F. With this construction the flanged plate E may be adjusted eccentrically to the shaft more or less, to control the bodily horiently explained.

To the shaft F there is fixed a crown gearwheel, Hfthe teeth of which are arranged eccentrically to the shaft, and this wheel H meshes into a long pinion, 1, fast on a driving;shaft, J, journaled in the frame G, and

- lraving a pulley, j, to which a power-transmitting belt will pass from any convenient motor.

The flanged eccentric plate E and the eccentric crown gear-wheel H will be set to give an accelerated horizontal motion of the pan A toward its front head corner, B, in direction of the arrow Z), and by adjusting the eccentric plate E any required extent of bodily throw may be given the pan in this direction, as the class of ores being separated mayrequire.

The front end, A, of the pan is provided,

rest loosely on the tops of the large heads We of screws K K, which are threaded into lugs 99 of the frame G, and are provided with stop or jam nuts 76 k. By adjusting the screws K K the front end, A, of the pan may be raised to give the desired inclination from said front end to the rear end, 0, and also to give the desired inclination to the front end of the pan from its tail corner, B, to its head corner, B. A preferred downward incline or pitch from B to B is about one-quarter of an inch to the foot; but the front end of' the pan will be inclined this way more or less, as the ores being worked shall require. The gimbal ring D will slip on the flange e of the eccentric plate E, to allow any necessary adjustment of the head of the pan, as above described, and also to accommodate vertical adjustment of the end 0 of the pan, as next explained.

To the pan A, at its end 0, is fixed an arm, L, the outer part of which is bowed, and at the extremity of the arm there is swiveled a shoe or bearing-block, M, which is adapted to slide in the grooved head a of a screw, N,

which is provided with a jam or look nut, n,

zontal throw of the pan, for purposes prespreferably, with fixed bearer-feet a aflwhich and thereby vertically adjust the end 0 of the pan A, to give any necessary downward inclination to the pan from its front end toward its rear end. A preferred inclination of the pan in this way is about five-sixteenths of an inch to a foot; but the incline 0r slope may be varied by vertically adjusting the screw N V and setting it by the lock-nut n, as the class of ores being worked may require. This means for supporting the end 0 of the pan 1 not only allows vertical adjustment of the pan at that end to give it proper slope, but also provides for giving this end of the pan a greater or less extent of lateral throw toward and over the mineral-box P, which is supported by suitableleg-frames, p, or otherwise,

beneath the head A of the pan,to receive the washed and graded mineral from the pan. It is obvious that when the back end, 0, of the pan is set vertically the screw N may belocked by the nut n, so as to hold the groove or slideway of the screw-head n at any desired angle to the stroke-line of the pan; hence when the head n is locked in the position shown in full lines in Fig. l the head of the pan at or toward its end 0 will receive very much less lateral movement in direction of the arrow 0 than it will receive when the head a of screw N is adjusted at a greater angle to the stroke-line of the pan, as shown in dotted lines. The

5 lateral bodily movement of the back end of the pan in direction of arrow 0 is given as the panis thrown or carried with accelerated movement in the direction of the arrow 1) by the eccentric gearing above described; hence 0 this lateral motion of the back end of the pan will likewise be a comparatively quick one, and as the block M may be adjusted to a nieety to move at any angle to the general.

stroke-line of the pan, the finer ores passing 5 toward the tail of the pan may be effectively separated and graded, as well as the coarser ores at and toward the head of the pan.

The tailingsbox R is supported on suitable 5o leg-frames, r, beneath the tail edge A of the pan, and has a discharge-spout, S, and the back ends of the mineral-box P and the tailings or refuse box It will preferably be 0011- nected by-a conduit, T, having an opening at t into the box 1? at about half the height of the box, and another opening at 25 into the.

box It, whereby excess of water may pass off from the mineral-box to the tailings-box, and.

thence out at the spout S. 7

Water is supplied to the pan from a pipe, U, which ranges along and about parallel to the head A of the pan, and just back of where 'the head-apron a bends down from the main body of the pan. This pipe U will be con- 55 nected to any source of water-supply at its end a by a flexible tube or pipe, allowing agitation of the pan, and the water will be delivered from pipe U into the pan in graduallydiminishing quantity or volume from the front end toward the back end of the pan, either by means of holes V of like size made in the pipe U at increasing distances apart toward the tail of the pan, or by holes V having gradually smaller sizes toward the back end, 0, of the pan, and placed at like distances apart along the pipe, or by holes V made gradually smaller and also spaced farther apart toward the back end, 0, of the pan, as may be preferred.

This graduated supply of water to the pan A allows the" coarser and finer ore particles on the pan to be thoroughly washed with a minimum quantity of water, thereby not only avoiding waste of the water, but also prevent ing a washing and waste of the finer valuable ore particles back over the apron a into the box R with the gangue or tailings.

The continuous operation of the machineis as follows: The crushed ore or ganguc from the stamps will be fed onto the pan A- through a box or chute, W, located at the front end of the pan, about over the driving-shaft J, it being understood that the plate E had been set to give the desired extent of bodily throw of the pan in direction of the arrow 1), and that the pan had been set to incline properly from B to B, and from B B to G,and that the slideblock bearing Nnhad been adjusted at proper angle to give the desired extent of lateral throw to the back end of the pan in direction of the arrow 0. As the pulp or gangue flows toward the back end, 0, of the pan, the quick or no celerated movement of the pan towardits hi gh est point 13, in direction of the arrowb, will carry or throw the heavier particles of ore toward that point, and the lighter ore particles will arrange themselves lower down the slope, according to their weight, and the current of water from the pipe U will wash all the worthless'or comparatively worthless material over the apron a of the pan into the tailings-box R, while the valuable mineral, by the forward impetus or momentum of the pan in direction of arrows I) and 0, will be carried over the head-apron a of the pan into the mineral-box P in condition for smelting. The bearerscrews K K and N may be adjusted vertically at any time to alter the inclinations of the pan while the machine is running,to regulate the washing, concentration, and separa tion of the ores more closely as the work pro grosses.

It is obvious that the valuable mineral will not only be concentrated, but will be separated or graded into different sizes in the box 1?, with the larger particles at and toward the front of the pan, and the successively smaller particles ranging toward the back end, 0, of the pan. The failings or refuse will also be graded into different sizes in the box R, thus allowing the larger particles to be removed together and stamped or reduced for subsequent treatment, to recover what of value there may be in them.
